The Lethbridge Herald (Newspaper) - January 9, 1974, Lethbridge, Alberta Wednesday, January 1t74 THI LETHMIDOC HERALD 27 Hydrogen may be tomorrow's fuel OTTAWA (CP) Motivated by the energy crisis, National Research Council scientists are devising a model for using hydrogen as a fuel for running cars, heating homes and even generating electricity. The scientists are involved mainly in research on hydrogen storage, a problem that has been a serious draw- back to the widespread use of hydrogen as a fuel. The technology for converting the country to hydrogen as the principal energy source is either available or close at hand, Dr. Tom Ledwell said Tuesday in an interview. Whether it would be practical to do so was another matter. The main research project was to find a safe, convenient way to store hydrogen, a gas- eous element so light that a pound of it occupies about MO cubic feet. As a fuel, though, that pound has times the heating ca- pacity of a pound of gas or home-heating oil, said Dr. Ledwell, a research officer in the NRC's fuels and lubricants laboratory. To make hydrogen storage economically feasible, the scientists propose to store it in containers filled with powdered metal, he said. The metal would act as a sponge for the gas which could then be stored at twice the density of liquid hydrogen. The container, heated at controlled temperatures, would release the hydrogen, just as steam escapes from heated water. LIQUID OUT Liquid hydrogen is not prac- tical for storage because it has to be cooled to -400 degrees Fahrenheit. The cool- ing process requires much energy and the frigid liquid would kill anyone touching it, said Dr. Ledwell. Hydrogen could be produced in mass quantities through electrolysis, a process that separates hydrogen and ox- ygen from water. Hydroelectric stations could supply both the electricity and water for process. However, there would be bugs in such a system, including the problem that 90 per cent of the power would be CUBA WANTS TO BURY HATCHET? Family outing Prime Minister and Mrs. Trudeau and son number two, Sacha, head through the halls of Parliament for home after the first official outing of mother and son since the baby was born Christmas Day. They had attended a state dinner for Gov.-Gen. and Mrs. Roland Michener, leaving office this week after seven years in Government House. WASHINGTON (AP) -The United States expressed cautious interest Tuesday over reports that Cuba is interested in ending the diplomatic estrangement between the two countries. "We are not dismissing them. We will weigh state depart- ment spokesman George Vest said following statements by Cuba's ambassador to Mex- ico, Fernando Lopez Muine, that Cuba is willing to begin talks with the U.S. on re- newing diplomatic relations as soon as Washington lifts its 12-year-old economic block- ade of Cuba. Vest said, however, that he would not want to "jump to the conclusion" that Lopez' statements constituted a significant change in Cuban policy. He referred reporters to of State Henry Kissinger's news conference two weeks ago in which he said "the major obstacle to rapprochement has been the hostility of the government of Cuba and its commitment to revolutionary policy throughout the western lost in the conversion process, he laid. The hydrogen could then be piped from producing sites to storage Transporting it this way would be more eco- nomical than transmitting electricity through wires, he estimated. Scientists in Europe were also experimenting with methods of producing hydrogen directly from uranium fission in nuclear power stations. An attractive feature of operating a car from a hydrogen container was increased efficiency. About 60 per cent of car fuel was wasted in heat, but some of the heat could be used to regulate the hydrogen flow from the container. Powdered magnesium now is being tested in NRC labora- tories for its ability to absorb hydro Alloys jrdrogen gat in storage. ys of nickel, iron sod the rare earth metals might also be used, said Dr. Ledwell. COMBUSTION RELIABLE Although hydrogen ii readi- ly flammable, scientists say its combustion characteristics are relatively reliable. It is no more likely to explode un- predicably than natural gas, they way. NRC scientists are also con- sidering a proposal to begin experimental research with water-oil mixtures as fuel. The mixtures apparently burn more efficiently and clearly than straight petroleum. U.S. researchers have developed fuel emulsifiers that will mix water and oil in a one-to-three ratio for use in heating plants and car engines. Lopez, in a meeting with a group of reporters Monday, said Cuba has shelved its de- mand for the United States to give up its naval base at Guan- tanamo Bay, on the south coast of Cuba. As for the blockade, Lopez said it has been made ridicu- lous by Cuba's trade with Ja- pan, Western Europe and other parts of the world.
